Screen space terrain

Lastest days I’ve been busy coding a demo of a “screen space terrain”. There isn’t geometry here, only heightmaps. A grid is projected over a plane by a projector camera (in red). At now I’m trying to fix vertex interpolation and making a more better projector. Frame rate is constant because the projected grid has the same size along the scene.
When I finish it, I’ll upload a demo with full source code.

    Can you explain a little bit more this technique? Thanks :)

    I used the concept of projected grid that I saw in the famous water demo .
    After I have the idea of using the technique for terrain I found this paper.

    Hope it helps for the moment :)
